Video: Ten Little-Known Facts About Justin Bieber on 'Letterman'

In an effort to launch his new perfume for women called 'Someday', Bieber allowed himself to be the butt of Letterman's jokes.

Justin Bieber came back to "Late Show with David Letterman" on Wednesday, June 22 to read out the ten little-known things about him. After he entered the stage, David Letterman teased him of his age and joked about the teen singer not knowing who he is. "You don't stay up this late, do you?" Letterman asked him jokingly.

Bieber began his list by promoting his women fragrance, "Someday", which he said can be used as low-cal salad dressing. Then he continued with "I served eight months in prison for siphoning gas", "The first that I bought when I hit it big was a four-slice toaster", and "As hard as I've tried, I don't know how not to be adorable". Letterman quipped about the latest, "Gotta spend the day with me".

Like other celebrities who read Letterman's list, Bieber also made fun of the show. He said at number four, "I begged my publicist to get me out of this." From there the laughter kept rolling with the pop sensation saying, "My mom had to remind me that he's not Larry King," while nodding over Letterman.
